Founders Agreement Template: What to Include and Why Every Co-Founder Team Needs One

Most co-founder disputes aren't about strategy or vision — they're about things that were never written down. Who owns how much? What happens if one founder leaves in year two? Who has the authority to sign contracts or hire employees? A founders agreement answers these questions before they become arguments.

The founders agreement is one of the most important documents a startup creates, and one of the most commonly skipped. The founders are aligned, the product is exciting, and formalizing the relationship feels premature. By the time a dispute arises — and in many co-founder relationships, one eventually does — the absence of clear written terms makes resolution exponentially harder.

What Is a Founders Agreement?

A founders agreement is a contract between the co-founders of a startup that establishes the fundamental terms of their working relationship: who owns what percentage of the company, what each founder's roles and responsibilities are, how major decisions are made, and what happens if a founder leaves.

The agreement is typically entered into at or near formation — before the company raises outside capital, before significant IP is created, and before the team grows beyond the founding group. Its purpose is to align expectations while all parties still have equivalent leverage and good intentions. Trying to negotiate these terms after one founder has contributed significantly more than another — or after an investor is asking hard questions about founder equity in due diligence — is far more difficult.

A founders agreement is distinct from the company's organizational documents (articles of incorporation, bylaws, operating agreement). It's a founders-to-founders contract that governs the relationship between the people building the company, not just the company itself.

Founders Agreement vs. Founders Stock Purchase Agreement

These two documents are related but serve different functions, and both are typically needed in a properly structured startup.

A founders agreement (sometimes called a co-founder agreement) is a comprehensive governance document that covers roles, equity allocation, decision-making authority, IP assignment, confidentiality, and exit provisions. It governs the founders' relationship with each other.

A founders stock purchase agreement (FSPA) is the specific legal instrument through which founders actually receive their equity in the company — their shares of common stock. The FSPA typically includes the purchase price (often a nominal price reflecting the early stage), vesting schedule with cliff, repurchase rights the company holds while shares are unvested, and transfer restrictions. It is the mechanism that makes founder equity real and subject to vesting.

Many startups use both: a founders agreement to document the relationship and a stock purchase agreement to formalize equity issuance. Some use a single combined agreement. What matters is that the key terms are documented before any founder contributes significant work or value.

What to Include in a Founders Agreement

Equity Ownership and Allocation

The agreement should explicitly state each founder's equity percentage at founding. This sounds obvious, but many early-stage teams operate with an informal understanding of "roughly equal" that later produces disputes when the actual percentages are formalized. Document the precise split — and document why. If one founder is contributing more capital or IP, the rationale should be in writing.

Note that the equity percentages at founding are usually subject to vesting — meaning founders don't fully own their shares until they've earned them through continued service.

Vesting Schedule and Cliff

Vesting is one of the most important protections for both founders and investors. Standard founder vesting is a four-year schedule with a one-year cliff — meaning a founder must remain with the company for at least one year before any shares vest, and the remaining shares vest monthly over the following three years.

Vesting protects the other founders and the company if one co-founder leaves early. Without vesting, a departing founder could retain their full equity stake even after contributing for only a few months. Investors nearly universally require founder vesting and will often reset or reduce credit for time served if the founders haven't already implemented it by the time a round is raised.

The agreement should also address what happens to unvested shares if a founder is terminated, leaves voluntarily, or is bought out — and whether the company has a right to repurchase at original cost or fair market value.

Roles and Responsibilities

Define each founder's role (CEO, CTO, COO), primary responsibilities, and whether the role carries operational authority. This doesn't need to be an exhaustive job description, but it should establish who has authority over key areas: product, engineering, sales, finance, legal, and people operations.

Role clarity is particularly important in technical co-founder relationships where one founder is building the product and the other is building the business. Ambiguity about who makes what decisions creates friction that compounds over time.

Decision-Making Authority

The agreement should define which decisions require unanimous consent, which can be made by majority vote, and which individual founders can make autonomously within their role. Common categories:

• Unanimous consent: issuing new equity, raising capital, selling the company, taking on significant debt, adding new co-founders
• Majority vote: major hires, strategic pivots, significant expenditures
• Individual authority: day-to-day operational decisions within each founder's domain

Without this structure, every meaningful decision becomes a potential flashpoint, and the team defaults to either group paralysis or unilateral action — both of which create problems.

Intellectual Property Assignment

All IP created by founders in connection with the company — code, designs, algorithms, brand assets, written materials — must be assigned to the company, not retained personally by the founding individuals. This is non-negotiable for investors and essential for the company to have clear ownership of its core assets.

The IP assignment should be written and comprehensive. Founders who created foundational technology before incorporation should execute a separate IP assignment agreement or clearly address the transfer of pre-company IP in the founders agreement. Ambiguity about who owns the core technology is one of the most serious issues a startup can face in due diligence.

Departure Provisions

The agreement should address three departure scenarios: voluntary resignation, termination for cause, and termination without cause. For each, the key questions are: what happens to unvested shares (typically forfeited or repurchased by the company), what happens to vested shares (typically retained), and what non-compete or non-solicitation obligations apply post-departure.

In states like California where non-competes are generally unenforceable, the agreement should be drafted accordingly. In Texas and other states where they are enforceable with reasonable scope, the terms need to be carefully calibrated to be defensible.

Confidentiality Obligations

Founders should have written confidentiality obligations to the company that survive their departure. This is particularly important for technical co-founders who have access to proprietary code, architecture, and product roadmaps.

Common Founders Agreement Mistakes

Skipping it entirely. The single most common mistake. "We trust each other" is not a founders agreement. Trust is not what founders agreements are for — they exist precisely for the scenarios where trust breaks down.

Equal equity without vesting. Equal splits aren't wrong, but equal splits without vesting leave the company exposed if one founder exits early. All founders should vest regardless of how the equity is split.

No IP assignment. Founders who retain IP personally — or who don't clearly assign pre-company IP — create a problem that can block future funding rounds and acquisitions.

No departure provisions. Founders agreements without clear departure mechanics leave co-founders and investors uncertain about what happens when a founder leaves, reducing everyone's confidence in the long-term stability of the team.

Treating the agreement as permanent. A founders agreement reflects the relationship at founding. As the company grows and roles evolve, the agreement may need updating — particularly if founders take on new responsibilities or if the equity split changes through a formal restructuring.

Using a Template vs. Working with an Attorney

A founders agreement template can cover the essential provisions for a two-person founding team in a standard startup situation. Promise Legal offers a founders agreement template that addresses equity, vesting, roles, IP assignment, decision-making, and departure provisions.

Attorney involvement is worth the investment in several situations:

• One founder is contributing significant IP, capital, or other assets that require careful valuation and documentation
• The founding team includes more than two people with non-standard equity arrangements
• Any founder has prior employment agreements with IP or non-compete provisions that may affect their contributions
• The company plans to raise capital within the next 12 months and needs the founding documents to be investor-ready
• There are cross-border or multi-jurisdiction complications (founders in different states, international contributors)

Actionable Next Steps

• Sign the agreement at or before formation, not after. The longer you wait, the more leverage any individual founder has and the harder the conversation becomes.
• Implement vesting from day one. If the company is already formed and founders haven't implemented vesting, restructure the equity before raising capital — not during the term sheet negotiation.
• Execute an IP assignment agreement alongside the founders agreement, covering both current and pre-company IP.
• Revisit the agreement when roles change significantly — when a new co-founder joins, when an existing co-founder's role changes materially, or before a priced fundraising round.
